Estimating the Components of a Wetland Water Budget
… quantitative understanding of the wetland water budget in order to estimate the amount of water available to the wetland over time. Many methods exist to estimate each component of the wetland water budget. In this study, monthly values of the water budget components namely, precipitation, …

Evaluating a Process-Based Mitigation Wetland Water Budget Model
Correctly predicting water levels is key to the success of created wetlands. The Pierce method is a commonly used technique for modeling and designing mitigation wetlands that assumes minimal groundwater interaction with the wetland. This technique for mitigation wetland design relies primarily on …

Modelling water budget at a basin scale using JGrass-NewAge system
Water resources availability and its variability is one of the most pressing global problems. Hydrological models are useful to understand the water balance of a basin, providing information for water resource forecast, assessment, and management. The effectiveness of the models in estimating the …

Estimating the water budget of extratropical cyclones with the precipitation efficiency
Estimating the water budget of three mid-latitude extratropical cyclones is attempted from the perspective of the precipitation efficiency (PE), using a method proposed for the study of convective columns. Using a lagrangian, system-relative volume centered on the surface low pressure, each cyclone …

Evaluation of a Water Budget Model for Use in Wetland Design
… As a result, correctly estimating the wetland water budget, is essential to the success of created wetlands. A wetland water budget model, Wetbud, was developed by collaborators from Virginia Tech, Old Dominion University, and the Technical University of Crete for estimating wetland water …

Estimation of a water budget for Agnes Marsh, Grand Forks County, North Dakota
… hydrological impact to the marsh by a declining water table in the aquifer. The purpose of this study was to determine how Agnes Marsh interacts with the underlying Elk Valley aquifer and how sensitive the marsh is to declining water levels in the aquifer. </p><p> Three methods were used to …

Investigating the Water Budget and Subsurface Hydrology of Two Rain Gardens in Calgary, Alberta
… impervious surfaces that prevent stormwater from infiltrating into the soil. Rain gardens are a form of low impact development technology that mitigate some of these effects by promoting natural stormwater infiltration. Rain gardens have extensively been researched in warm and humid …

Evaluation of a Water Budget Model for Created Wetland Design and Comparative Natural Wetland Hydroperiods
… Regulatory approval requires a site-specific water budget that predicts the annual water level regime (hydroperiod). However, many studies of created wetlands indicate that post-construction hydroperiods frequently are not similar to impacted wetland systems. My primary objective was to …

Hydrogeology and Simulated Water Budget of the Rio Cobre and Rio Minho-Milk River Basins, Jamaica, West Indies
… quasi three-dimensional finite-difference groundwater flow model was used to conceptualize flow conditions and establish a hydrogeologic budget of the region. The Rio Cobre and Rio Minho-Milk river basins lie on the Clarendon Block, an area with a complex geologic history. The geologic history …

Balancing the Water Budget: the effect of plant functional type on infiltration to harvest ratios in stormwater bioretention cells
Stormwater bioretention cells (BRCs) are a variety of green stormwater infrastructure with the potential to restore pre-urban water balance, provided they can be tailored to infiltrate and evapotranspire (i.e., harvest) urban runoff in proportions consistent with pre-urban hydrologic conditions. …

Pairing Quality and Quantity in a Mass Balance of Water in California
Whether there is enough water in California to meet the needs of residents, businesses, agriculture, and the natural environment, now and in the future, is important to Californians. One of the tools used to assess water availability in California is the water budget, which quantifies how much …

Using Water Budgets and Isotope Analysis to Explore Water Availability in Low Flow Conditions: Hartley Pond Case Study
… seasonal changes to the volume and timing of water flowing through a reservoir provides valuable information for responsible resource management. Hartley Pond is a reservoir in Duluth, Minnesota, that is formed by a dam on Tischer Creek. Solar forcing to the reservoir elevates the summer water …

Economic Analysis of Infrastructure Investment and Irrigation Budget Issues in a Southwestern U.S. Water Utility
… investigate two policy issues faced by water utilities: infrastructure investment and water budget programs. Water utilities have infrastructure that is deteriorating at an increasing rate, necessitating higher rates of investment from ratepayers. At the same time utilities must improve …

A Conceptual Model OF Groundwater Flow in Spring Valley, NV, AND Snake Valley, NV-UT
… the Clark, Lincoln and White Pine Counties Groundwater Development Project proposed by the South Nevada Water Authority (SNWA). Water budget estimates suggest that interbasin flow accounts for a significant portion (~25%) of the water budgets in Spring and Snake Valleys. Although interbasin flow …

Climate variability and drought in the South Platte River Basin
… has been identified as an area experiencing water overuse, making conflicts and shortages likely during times of drought. This study used multiple sources of climate and water consumption data to better understand climate and water consumption changes during drought: North American regional …

Improving Site Quality Estimates in the Upland Hardwood Forests of the Southern Appalachians with Environmental and Spatial Modeling
… Mountains of North Carolina were related to the water budget. Specifically,the hypothesis that site index could be predicted by variables that represented the inputs, usage, and supply of water was tested. A second hypothesis questioned if site quality classes could be predicted by a combination …

Evapotranspiration Measurement and Simulation due to Poplar Trees at a Phytoremediation Site
… system and then determining the effect on groundwater flow. This will be accomplished by quantifying evapotranspiration using a water budget, applying White's Equation, comparing groundwater recession curves, creating a groundwater flow model, and examining water table elevations obtained at the …

The Effectiveness Of A Specifically Designed Green Roof Stormwater Treatment System Irrigated With Recycled Stormwater Runoff to Achieve Pollutant Removal and Stormwater Volume Reduction
One of our greatest threats to surface-water quality is polluted stormwater runoff. In this research, investigated is the use of a green roof irrigated with recycled stormwater runoff to remove pollutants from stormwater runoff and reduce the volume of stormwater runoff leaving developed areas. The …
